SPEQIFICATION forming part of Letters Patent No. 409,795, dated August 2'?, 1889. Application tiled November 11, 1884. Serial No. 147,652. (No model.) Patented in Canada February 25, 1885, No. 21,150.

To @ZZ whom, t may concern.-

Be it known that I, SAMUEL D. MADDIN, a citizen of the United States, and a resident of Miamisburg, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Grain-Binders, (which invention has been patented in Oanada by Patent No. 21,150, dated February 25, 1885,) of which the following is a specification.

My invention relates to improvements in apparatus for bindin,f. grain, and has for its objects to simplify the construction and operation of such apparatus, to reduce the weight and number of parts and the friction, and to properly direct the grain to and discharge the bundle from the packing mechanism 5 and these objects I effect by means of the appliances and the arrangement thereof, hereinafter fully set forth, and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation, in part section, of my improved binder. Fig. 2 is a part sec- -tional plan of Fig. 1, the platform and parts above it being removed. Fig. 3 is a part sectional plan of the overhan ging arm and parts carried thereby. Fig. 4' is a plan of the end of the overhanging arm. Fig. 5 is a perspective view showing the parts ofthe apparatus below the platform. Fig. G is an elevation in part section, looking in the direction of the arrow a, Fig. 1. Fig. '7 is a perspective view of the upper part of the overhanging arm and parts carried thereby. Fig. S is a detached view of the knotter and device for throwing off the loop; Fig. 9, a detached view of the pawl-lever and operating-bar. Fig. lO is a detached view of the cord-controller lever and operating-bar. Fig. 11 is a front view showing a harvester with my improved binder and the grain elevator and conveyer. Fig. 12 is a plan of part of Fig. 11. Fig. 13 is a detail view illustrating one` of the horizontal strawconveyers.

The platform A is over-hung by an arm B, the vertical portion a of which is at the side of the platform and the horizontal portion Z) of which carries the knotting mechanism@ that is, all the appliances for directing the cord carried by the needle for forming it into anknot and for severing the cord. Below the platform is a frame D, suitably constructed to afford bearings for shafts or studs F. F G II K J, the shafts E, F, and G beingparallel to the overhanging arm B, the shaft K rotating at right angles to the shaft G, and the shafts Il and J, which are parallel to the shaft G, being rock shafts or bearings for levers and arms, as hereinafter set forth. The shaft H carries the needle-arm L, and the platform A, above the latter, is slotted to permit the arm to rise and fall above and below the platform, and a connecting-rod L extends from a crankpin L2 upon a disk G', secured to the shaft G, to short arms c c, projecting from the hub of the needle-arm, so that the rotation of the disk G is made the means of vibrating the needle-arm between the limits indicated in full and dotted lines, Fig. l.

l To the shaft II are hung two arms M M, constituting the compressor, andto ears e, at the outer ends of said arms, are jointed the upper links f j' of toggle-levers, the lower links g of which are jointed to a horizontal lever I', hung to a stud I and connected at the outer end to a bar 12, carrying a nut 13, between which and a stationary bearing 15 of the main frame intervenes a coiled spring 14. In combination with the toggle-support for the compressors, I employ a trip operated positively and independently of thelneedle from the intermittently-moved disk G', said trip being adapted to move said support and thereby permit the compressors to recede ,be-1,A y low the binder-platform, and such a tripping mechanism I will now describe. A link g is hung to a pin f, connecting the links f and g, and is connected at the outer end to a bar g2, extending between two arms g3 g3 upon the shaft J, which carries the discharge-arms J the latter extending back beyond the shaft H, as shown in Figs. 1 and 2. To the bar g2 is connected a rod F which is attached at the inner end to the pin of a crank F2, upon the end of the shaft F, and a pinion F3 upon the latter gears with a toothed segment F4 of the disk G. As thc pinion F3 revolves in the direction of its arrow, Fig. 1, the rod F will be drawn back in the direction of its arrow and the shaft J will be rocked so as to throw the discharge-arms J above the plat- IOO form, (passing through suitable slots therein,) and at the same time the link g will be thrust back, so as to bring the toggle-links f g at an angle to each other, thereby swinging the compressor-arms M upon the shaft H and carrying the compressor below the platform as the discharge arms rise through and above it. The toggle-joint arrangement above described serves to lock the compressorarms in place, so as to resist the thrust or pressure of the gavel upon them, the centers lf' 3 being in line, Fig. l, when the arms are elevated and holding the same immovably in position, except so far as a slight play is permitted by the yielding` of the spring 14, which is compressed by the nut 13 to such an eX- tent as to permit the arms to yield only when a destructive pressure is brought against them. When the bundle is to be discharged, the backward draft of the connecting-rod F' causes the center f to be carried to one side, when the arms will be unlocked and will swing downward to the position shown in Fig. 5 and the discharge-arms will be elevated, as shown in said ligure, throwing the bundle off from the platform.

As the compressor-arms are held stationary during the time that the needle-arm is rising' and the bundle is being tied and packed, the pinion F3 should occupy a stationary position at such time. I therefore construct it, as shown, with a delay-shoe x, which remains opposite the corresponding flat delay-surface of the disk G' until the lat-ter has turned to bring the rack F4 into gear with the teeth of the pinion, when the latter will be revolved one revolution and then be vagain locked in its previous position, this movement being sufficient to carry the toggle-levers out of line, depress the compressor-arms and elevate the discharge arms, then lower the latter, and again carry the compressor-arms to an elevated position and lock them in place.

The knotting device N may be of any suitable construction. As shown, it is a hook having a stationary and a movable jaw, as is common in devices of this class, and is carried at the lower end of a vertical shaft N', which turns in a vertical stud N2, pendent from the under side of the portion b of the overhanging arm B. The knetter normally occupies the position shown in Fig. 7, and is revolved in the direction shown by the arrow, Fig. 3, and is locked in position after each revolution by means of a reciprocating rackP and pinion P', the rack in the presentinstance constituting part of a frame P2, which slides in bearings in guides upon the overhanging arm, and the pinion P', having a flat face y, which when opposite the iiat portions of the rack-bar prevents the revolution of the pinion, thereby locking the knetter in its position while the motion of the frame continues. The pinion P is loose on the shaft N', and has two recesses with inclined faces, and two loose rolls q q, con stitu tin gaelutch, which Instead of dragging the knot off the end of the knetter, as heretofore, by the weight of the bundle or by the action of the dischargearm, I carry the loop positively over that portion of the cord clamped between the jaws, by means of a projection j upon a reciprocating' bar-as, for instance, on the lower longitudinal bar la of the frame P2, and I provide the lower jaw of the knetter with a longitudinal groove c', into which the projection j passes, so as to strike the loop of cord and carry it off of the jaws as the frame P2 moves in the direction of its arrow,Fig. 7.

The cord-holding disk Q is supported at the side of and a short distance from theknotter by an arm Q', pendent from the overhanging arm and carrying a stud 7, upon which the disk turns, the said disk being provided with notches, as usual, and its edge passing between clamp-plates m m, (best shown in dotted lines, Fig. 7,) carried by a bar R, hung to the side of the arm Q', and provided with a screw rod which passes through the arm Q', and carries a rubber disk or spring m' and a nut m2, so that the clampplates may be drawn toward the cord-holding disk with any desired degree of tension. At the side of the disk is a ratchet-wheel p, and upon the stud Z swings a lever Q2, provided with a pawl p', which engages with the teeth of the ratchet-wl1eel,and a bar P3 is hung to t-he frame P2 and bears upon a stud p2, projecting from the side of the lever Q2. (See Fig. 9.)

At the under side of the bar I3 are two projections s s', with an intermediate notch w, one side of the projection s' being inclined, as shown, and all being so arranged that when the frame P2 is at the limit of its movement in the direction of its arrow, Fig. 7, the stud p2 will occupy a position in the notch w. l/Vhen the frame P2 moves in the direction of its arrow, Fig. 7, the contact of the side of the projection s' with the stud p2 willcarry the lever Q2 forward until the disk Q is turned the distance of one tooth or notch, so as to catch the cord laid in it by the needle and jam the same between the plates fm, when the projection s' will pass over the stud p2, and the movement of the frame P2 will be continued until the revolution of the knetter is completed, and until aknife S, carried by the frame, cuts the cord, and until the projection j carries the loop of cord off of the end of the knetter. lVhen the frame P2 is carried in the direction of the arrow 2, Fig. t), the bar P3 will slide over the stud p2 until the projection s' is carried over the stud and the latter is again brought into the notch w, when the projection s, striking the stud, will IOO IIO

cause the lever Q2 to be carried to its iirst position.

In order to insure the folding of the cord downward over the side of the knetter, so as to be caught and properly form the loop when the knetter revolves, I use a vibrating lever T, having` two arms fr r at right angles to eachother and pivoted to an arm of the stud N2, so that it may be brought to either of the positions shown in full and dotted lines in Fig'. 10, and so that when it swings downward, after the needle has been brought to the position shown in Fig. 6, its long arm will cross the cord beneath the needle, and will carry the Vsame down against and below the knotter-jaws. The movements of the lever T are imparted by the contact of a stud t withthe arms r r', the said stud being carried by a bar T', secured to the frame P2, the stud upon the first movement of the frame P2 striking the arm r and causing the lever T to swing rapidly to its lowest position before the rack P engages with the pinion P. The lever T is carried back to its first position by the contact of the stud t with the arm r.

The frame P2 is caused to slide back and forth by the vibration of a lever U, pivoted to a stud 5 upon the standard a, the lever being connected to the sliding frame by a connecting-rod U and the parts all being arranged as shown, so that thc operating movements of the knetter devices-that is, the knetter-jaws, cord-clamp, cord-controller or lever T, knife, and dischargestud-are all effected asthe frame P2 is drawn in the direction of its arrow, Fig. 7 I thus avoid the lost motion and uncertain' actions that would tend to result if the movements were effected by the thrusting action upon the connecting-rod,which, under such circumstances, would tend to buckle or bend.

By driving all the knetter devices from a reciprocating frame carried by the overhanging arm I avoid the necessity of shafts or gears between the knetter devices andl the drivingshaft below the platform, so that the movements are not only less complex, but there is less lost motion and strain.

The vibration of the lever U is effected from the disk G through the medium of the shaft K, pinion K', segmental rack K2 upon the wheel G', crank K3 on the end of the shaft K, and connecting-rod K, the rack K2 being so arranged upon the disk that the shaft K will be turned and the lever U swung to draw back the frame P2 after the needle L has attained its upward and forward position.

By the use of a lever vibrated by means of mechanism below the platform and of a frame carried by said lever above the platform and constructed to operate the various devices carried by the overhangin g arm I am enabled to dispense with the customary series of gears and shafts between the parts above and below the platform, and thereby greatly reduce the weight of the machine and the friction and noise in operating the parts and render it much more simple and less liable to get out of order.

The disk G is driven from a pinion E upon the driving-sh aft E, which pinion meshes with teeth u upon the periphery of the disk, the motion of which is of course arrested at proper intervals by means of the ordinary stop device used in this class of machines, and not necessary to be here described.

'It will be seen that by the construction described I am enabled to impart all the movements required to the devices, both below and above the platform, from a single operatingdisk 'G, thereby avoiding a multiplicity of shafts and connections and correspondingly reducing the friction and weight.

In connection with the machine constructed as set forth I employ packer-arms V, which are arranged above the platform'A and are connected, as usual, to the cranks V of a double-cranked packer-shaft V2, each of the arms having a slot yv, to receive a guide-bar fu', supported by the overhanging arm of the machine.

Vhile the shaft V2 may be driven through the medium of a suitable chain or gears from the shaft G, I prefer to drive the shaft V2 from one of the shafts of the harvester to which the binder is applied, thereby taking the weight and strain off of the binder, and avoiding the necessity of operating any part of the binder devices except during the operation of knotting the cord and throwing off the bundle.

The machine described may be arranged upon the harvester in an inclined position, as usual; but I prefer to arrange it horizontally between the elevator and the outer wheel of the harvester, in which case the elevator will carry the grain to the platform, the packers will carry it over the platform against a compresser arm, and the discharge arms will throw the bundle from the platform over the wheel. An effective arrangement of this character is illustrated in Fig. l1, which. represents a harvester provided with two drivingwvheels 7l and 8, an axle l0, supporting an intermediate platform 9, and standards ll, upon which the binder is supported. An elevator NV carries the grain from the cutterframe G5 to a horizontal carrier If, arranged between the upper end of the elevator W" and the inner edge of the binder-platform A. The elevator IV is constructed substantially as set forth in my application, Serial No.l34,776, filed June 13, 1884; but the intermediatev carrying device, instead of consist-ing of sprocketchains turning upon vertically-arranged pulleys, consists of horizontal pulleys l2 13, carrying chains 1i, provided with the usual jointed feeding-teeth l5, (see Fig. 13,) the pulleys l2 being driven through the medium of suitable gear from the shaft of one of the upper elevator-rollers, and these shafts being carried by a frame Q7, hinged at its inner end near to the edge of the platform A and at its outer end to the frame of the elevator IV.

Vhile I do not wish to be limited to any particular style of conveyer having jointed feeding-teeth for use in connection with the horizontally-arrangcd pulleys just described,

that form shown in Fig. 13 operates satisfactorily. In said figure each alternate link of the chain 14 isv shown as being centrally open to engage with the sprockets on the pulleys, while the remaining links have pivoted thereto the feeding-teeth l5, each of which is provided with a laterally-proj ecting arm adapted to ride upon the rail l5', and be thereby held in an upright position to engage with the advancing grain. It will of course be understood that the portion of the chain which travels against the moving stream of grain has not arranged adjacent thereto a rail l5', so that the teeth are free to fold or lie down.

It is common in this class of machines to bring the butts of the grain against deecting-plates set at an angle for the purpose of moving the grain to one side or the other, which purpose is thereby but very inefficiently accomplished. I carry the grain between the elevator and the binding-platform .at any desired angle by making the pulleys 13 adjustable by securing them to a bar l0, capable of longitudinal adjustment, whereby the carrying-chains may be set at any desired angle, as shown in dotted lines, Fig. ll, the grain being thus positively conducted in its desired course. This is an important feature of my invention, as it, in addition to other advantages, avoids the necessity of shifting the position of the binder to properly receive the grain.

In order to permitthe cutter-frame to be set at any desired height and to lioat over the ground without interfering with the operations of the elevator and conductor, I hinge the lower portion of the frame of the elevator lV to the adjustable cutter-bar frame,

or to any of its connections, and the upper portion, as before described, to the frame Q7. In such case the vertical movements of the cutter-bar frame will simply alter the angle of the elevator and conductor frames to each other without interfering in any degree with their joint operation in conveying the grain from the cutter-frame to the platform, and without interfering with the lifting of the cutter-bar frame -to a vertical position to permit the -machine to be carried through narrow passage-ways.

By arranging the binder in a horizontal position above the supporting-wheels I am enabled to set it in line with the elevator and can conduct the grain in a continuous, nearly straight course without throwing it in front or to the rear of the wheels, as has been necessary heretofore in many cases.

By placing the binder between two drivewheels the Weight gives traction, there is less side draft, and the Width of the machine is reduced, as the reduction of side draft allows the horses to be placed nearer the side of the machine.

I have in this application shown some features also shown and claimed in my application, Serial No. 171,222, and I do not therefore here make any claim to these features.
